More on modern fuels

Hi All

I had not seen this before and gives an interesting insight into modern fuels in classic cars, there is also a book published apparently.

Fortunately for us 30 years of development between the XPAG and Lampredi engines! Not to mention SU carbs.

Kerosene has less calorific value than petrol, hence less power, not that I'd ever dream of putting it in a Beta.

A man with too much time on his hands! The point about using a Vacuum advance is a good one. I did this on my last beta spider converting a 2000 distributor because the advance curve is different to the 1600. Otherwise it makes the case for a mapped load aware advance curve. You get this with an FI install or with wasted spark + ECU + Throttle position sensor or MAP sensor. I think Chris Mace runs wasted spark with no distributor on his GC engine?

The 130TC did a version of this but the mapping might be off for modern fuel as the IE might be.

And the Lampredi engine (mercifully) has inlet and exhaust on opposite sides of the engne block, meaning exhaust heat soaking into the carbs is far less of a problem. It's an interesting piece of work, but the author repeats himself a lot and it's only fully applicable to a very limited set of classic cars. As Eric remarks, he clearly has too much time on his hands.
